Gas phase molecular spectroscopy is a powerful tool for obtaining information on the
geometry and internal structure of isolated molecules and their interactions with others. It …

This book presents a comprehensive overview of the modern theory of spectral line
broadening and shifting by pressure of atmospheric gases. It describes current semi …

N 2-broadened half widths and pressure shifts were obtained for transitions in the 2ν 3
methane band. Laboratory measurements recorded at 0.011 cm− 1 resolution with a Bruker …

This paper report nitrogen-and oxygen-broadening coefficients, their speed-dependencies,
and the collisional narrowing parameters of lines in the ν 4-band of methane. The …

In this paper we report line shape parameters of 12 CH 4 for several hundred 2ν 3
transitions in the spectral regions 5891–5996 cm− 1 (P branch) and 6015–6115 cm− 1 (R …

This paper presents a study of absorption in N2-broadened P and R manifolds of the 2ν3
band of CH4 near 6000cm− 1 using high resolution laboratory and atmospheric spectra …

The absorption spectra of mixtures of methane (CH4) with N2 and O2 at different partial
pressures of both CH4 and buffer gases for three temperatures 240, 267, and 296K have …

Lorentz air-broadened half widths, pressure-induced shifts and their temperature
dependences have been measured for over 430 transitions (allowed and forbidden) in the …

Raman spectroscopy is a promising method for the analysis of natural gas. It is necessary to
account for the broadening effects on spectral lines to improve measurement accuracy. In …
